This study is part of the search for solutions to the problems encountered in the manufacture and export of fish fillets. The production of fish fillets is mainly marked by a little mechanization. Thus, it is subjected to strong manipulation by the personnel, source of contamination. As a result, the search for thermotolerant coliforms, most of which are of fecal origin, makes it possible to assess the level of contamination of products and to judge the effectiveness of the hygiene measures taken by the fishnet production units. 190 preventive samples from 4 companies were studied. A survey was conducted to categorize the companies. Subsequently, the thermotolerant coliforms were counted on the violet crystal and neutral red (VRBL) bile lactose agar, inoculated in mass according to the French standard ISO 4832. It appears that of the 190 samples; 97.4% (185) of the results are satisfactory while 2.6% (5) of the results are unsatisfactory. The evaluation of the manufacturers of these nets indicated that there was a positive correlation between the number of serious defects and the unsatisfactory results. The result is that the best organized firms have the best laboratory results.
